THE FLORA OF NORTH AMERICA, 11 
Stockholm to send a botanist to Siberia and Iceland, which are 
on the same latitude as a part of Sweden, to collect seeds of plants 
as would “improve the Swedish husbandry, gardening, man- 
ufactures, arts, and sciences.” Dr. Linnzus suggested that 
North America would be a better country than either. About the 
same time a Captain Triewald gave in Stockholm an exhibition 
and lecture on his observations on silk-culture. As Linnzeus had de- 
scribed a species of mulberry* from North America and native of 
a climate similar to that of Sweden, this gave additional strength 
to the choice of North America. When Count Tessin, who could 
nearly always have his own way, and who was in favor of the 
project, became president of the Royal Academy, it was decided to 
send Professor Kalm. An appeal was sent to the three universi- 
ties of Sweden, at Upsala, Lund, and Abo, to contribute what 
they could for the advancement of science. Abo was the first one 
to answer, and sent a small sum, Lund had nothing to spare, but 
Upsala contributed liberally, considering the times and the coun- 
try. Now-a-days, $450 seem to us rather a smallsum. With the 
countributions from other sources, the fund amounted to about 
twice that sum. Professor Kalm, however, spent not only this 
and his own salary, but about $650 of his own money, and the 
journey left him with very limited means for the rest of his life. 
After passports had been secured from the courts of London, 
Paris, Madrid, and the Hague, Kalm sailed from Gothenburg the 
11th of December, 1747, accompanied by Lars Jungstrom, a gar- 
dener by profession. Overtaken by a severe storm, the vessel had 
to put in at Grimstad, Norway, where the travelers had to stay 
till the 8th of February, 1748. They arrived at London the 17th 
of the same month, stayed in England till August 15, and arrived 
at Philadelphia the 26th of September. 
In Philadelphia Kalm stayed about a month, and made there 
the acquaintance of John Bartram, the most prominent American 
naturalist at that time. Then he set out on a journey to New 
York, passing through New Frankfort, New Bristol, Pa., Bur- 
Trenton,
